Description

Technical Field

[0001] This utility model relates to the field of autoclaved aerated concrete block technology, and in particular to an autoclaved aerated concrete block. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks are a new type of building material with advantages such as lightweight, thermal insulation, heat insulation, and sound insulation. With the development of the construction industry, the performance requirements for building materials are constantly increasing. Traditional blocks can no longer meet market demands in some aspects, such as insufficient thermal insulation and complex construction. AAC blocks have emerged to address this need. Through a special production process, a large number of tiny pores are formed inside the blocks, effectively improving their thermal insulation performance. Furthermore, the lightweight nature of these blocks reduces the building's self-weight, which is beneficial for structural design and construction. In terms of environmental protection, they use environmentally friendly raw materials, have low energy consumption during production, and are environmentally friendly. Due to their excellent performance, AAC blocks have broad application prospects in the construction field.

[0003] A search revealed Chinese Patent Publication No. CN221422419U, which discloses a thermally insulated autoclaved aerated concrete (AAC) block. The block includes an AAC block shell, a moisture-proof and flame-retardant board, a thermal insulation layer, an AAC block inner body, a heat insulation cylinder, insulation cotton, a sealing plate, and a sealing assembly. Two moisture-proof and flame-retardant boards are respectively installed on both sides of the AAC block shell. The thermal insulation layer is disposed on one side of each moisture-proof and flame-retardant board. Two AAC block inner bodies are provided, each disposed on one of the two thermal insulation layers. The heat insulation cylinder is installed between the two AAC block inner bodies, and is connected through-hole to the top of the AAC block shell. This technical solution solves the problem of poor thermal insulation performance in existing technologies. However, in actual use, the structural connection stability between the bricks is poor, resulting in low overall wall strength. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an autoclaved aerated concrete block, which aims to improve the problem of poor structural connection stability between blocks in the prior art, resulting in low overall strength of the wall.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an autoclaved aerated concrete block, comprising a block body, wherein side fixing blocks are fixedly connected to both the left and right sides of the block body, and fixing strips are fixedly connected to both the front and rear sides of the block body; side recesses are provided on both the left and right sides of the outer wall of the block body, and long recesses are provided on both the front and rear sides of the outer wall of the block body; multiple slots are provided on the inner wall of the long recesses; multiple locking blocks are fixedly connected to the outer sides of the side fixing blocks and the fixing strips, and the slots engage with the locking blocks; a handle reinforcement mechanism is provided on the top plate of the outer wall of the block body, the handle reinforcement mechanism being used to facilitate the handling of the block.

[0006] Through the above technical solution, the side fixing block engages with the side recess on the upper side of the adjacent autoclaved aerated concrete block, and the upper groove engages with the locking block, so that the two adjacent autoclaved aerated concrete blocks can better mesh together, thereby improving the strength of the overall structure.

[0007] As a further description of the above technical solution:

[0008] The handle reinforcement mechanism includes two square slots, which are respectively opened on the upper and lower sides of the block body. A U-shaped column is provided on the inner wall of the upper square slot. The bottom of the U-shaped column penetrates the block body and is fixedly connected to a baffle. Multiple annular blocks are provided inside the block body, and multiple fixed columns are fixedly connected to the middle of the annular blocks.

[0009] With the above technical solution: when it is necessary to take out autoclaved aerated concrete (AAC) blocks, simply hold the U-shaped column and then take out the AAC blocks. When placing the AAC blocks in the desired position, lower the U-shaped column. The baffle will fall under its own weight, thereby causing the U-shaped column to retract into the inner wall of the AAC blocks. Furthermore, the overall strength of the AAC blocks can be improved through the ring block and the fixed column.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the block body is provided with anti-slip grooves on both the upper and lower sides, and the top of the block body is provided with multiple holes.

[0012] The above technical solutions can improve the contact area between bricks through anti-slip grooves and enhance the heat insulation and sound insulation capabilities of bricks through holes.

[0013] As a further description of the above technical solution:

[0014] Limiting posts are fixedly connected to the top four sides of the block body, and limiting holes are opened on the bottom four sides of the block body. The limiting posts are engaged with the limiting holes.

[0015] The above technical solution increases the stability of the upper and lower bricks by interlocking the limiting post and the limiting hole.

[0016] As a further description of the above technical solution:

[0017] A water pipe is installed on the inner wall of the hole on the left rear side, and a wiring pipe is installed on the inner wall of the hole on the right rear side.

[0018] The above technical solutions facilitate the connection to external water sources through water pipes and the laying of power lines through pipelines.

[0019] As a further description of the above technical solution:

[0020] A square groove is provided on the front right side of the block body, and a production date plate is fixedly connected to the inner wall of the square groove.

[0021] The above technical solution allows the production date of the brick to be marked using a production date tag.

[0022] As a further description of the above technical solution:

[0023] A notch is provided in the middle of the front side of the block body, and a gripping groove is provided on the top of the inner wall of the notch.

[0024] The above technical solution makes it easier for workers to move bricks by using the notch and the grip groove.

[0025] As a further description of the above technical solution:

[0026] A trapezoidal block is fixedly connected to the side of the fixing block and the adjacent side of the fixing strip. A trapezoidal groove is provided on the adjacent side of the inner wall of the side recess and the long recess. The trapezoidal block and the trapezoidal groove are engaged.

[0027] The above technical solution increases the interlocking force between adjacent bricks by interlocking the trapezoidal block with the trapezoidal groove.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the side fixing block and the adjacent autoclaved aerated concrete block are tightly engaged through the side notch, which enhances the connection between the blocks. The interaction between the upper slot and the locking block further improves the meshing effect of the adjacent blocks, improves the connection strength and the stability and durability of the overall structure, ensures the sturdiness of the building structure, can withstand greater loads, and enhances the strength and safety of the structure.

[0030] 2. In this utility model, autoclaved aerated concrete blocks can be grabbed by holding the U-shaped column, and then the blocks can be placed in the designated position. After the U-shaped column is lowered, the baffle falls due to gravity, causing the U-shaped column to retract into the inner wall of the block. The annular block and the fixed column together enhance the stability of the block, thereby making the bricks easier to pick up. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 3An embodiment of this utility model is provided: an autoclaved aerated concrete block, including a block body 1, with side fixing blocks 3 fixedly connected to the left and right sides of the block body 1, and fixing strips 4 fixedly connected to the front and rear sides of the block body 1. Side recesses 5 are provided on the left and right sides of the outer wall of the block body 1, and long recesses 6 are provided on the front and rear sides of the outer wall of the block body 1. Multiple slots 7 are provided on the inner wall of the long recesses 6. Multiple locking blocks 8 are fixedly connected to the outer sides of the side fixing blocks 3 and fixing strips 4. The slots 7 and locking blocks 8 are engaged. A handle reinforcement mechanism 2 is provided on the top plate of the outer wall of the block body 1. The handle reinforcement mechanism 2 is used to facilitate the handling of the bricks.

[0040] Specifically, the autoclaved aerated concrete block engages with the side recess 5 on the upper side of the adjacent autoclaved aerated concrete block through the side fixing block 3, and engages with the locking block 8 through the locking groove 7 on the upper side, so that the two adjacent autoclaved aerated concrete blocks can better mesh together, thereby improving the strength of the overall structure.

[0041] Reference Figure 3 , Figure 4 and Figure 5 The handle reinforcement mechanism 2 includes two square grooves 201, which are respectively opened on the upper and lower sides of the block body 1. The inner wall of the upper square groove 201 is provided with a U-shaped column 202. The bottom of the U-shaped column 202 penetrates the block body 1 and is fixedly connected to a baffle 203. Multiple annular blocks 204 are provided inside the block body 1. Multiple fixed columns 205 are fixedly connected to the middle of the annular blocks 204.

[0042] Specifically, when it is necessary to take out the autoclaved aerated concrete (AAC) block, simply hold the U-shaped column 202 and then take out the AAC block. When placing the AAC block in the desired position, put down the U-shaped column 202. The baffle 203 will fall under its own weight, thereby causing the U-shaped column 202 to retract into the inner wall of the AAC block. Furthermore, the overall sturdiness of the AAC block can be improved through the ring block 204 and the fixed column 205.

[0043] Reference Figure 1 , Figure 2 and Figure 3 The upper and lower sides of the outer wall of the block body 1 are provided with anti-slip grooves 9. The top of the block body 1 is provided with multiple holes 10. The top of the block body 1 is fixedly connected with limit posts 11. The bottom of the block body 1 is provided with limit holes 12. The limit posts 11 and the limit holes 12 are engaged. A water pipe 13 is provided on the inner wall of the left rear hole 10. A wiring pipe 14 is provided on the inner wall of the right rear hole 10.

[0044] Specifically, by setting anti-slip grooves 9, the contact area between bricks can be increased, thereby enhancing the stability of the overall structure. The anti-slip grooves 9 allow the bricks to be joined more tightly during assembly, reducing the possibility of slippage and improving the overall load-bearing capacity and durability. Furthermore, the holes 10 on the bricks effectively improve their heat insulation and sound insulation performance. The holes 10 not only reduce heat transfer but also absorb and block sound transmission, thus providing better heat insulation and sound insulation for the building. This is further enhanced by the limiting columns 11 and the limiting... The engagement of the positioning holes 12 and 12 further increases the stability between the upper and lower bricks. The cooperation between the limiting post 11 and the limiting hole 12 allows the bricks to be positioned more accurately when stacked, avoiding misalignment and loosening between the bricks and ensuring the stability of the overall structure. The water pipe 13 allows the bricks to be easily connected to the external water source. The wiring pipe 14 is also reserved on the bricks, which provides convenience for the laying of various lines. The wiring pipe 14 allows the wires and cables to be safely hidden inside the bricks, which is both beautiful and safe.

[0045] Reference Figure 1 , Figure 2 and Figure 3 A square groove 15 is provided on the right side of the front part of the block body 1. A production date plate 16 is fixedly connected to the inner wall of the square groove 15. A notch 17 is provided in the middle of the front side of the block body 1. A grip groove 18 is provided on the top of the inner wall of the notch 17. A trapezoidal block 19 is fixedly connected to the side of the side fixing block 3 and the side fixing strip 4. A trapezoidal groove 20 is provided on the side of the inner wall of the side notch 5 and the long notch 6. The trapezoidal block 19 and the trapezoidal groove 20 are engaged.

[0046] Specifically, the production date tag 16 can identify the production date of each brick, which facilitates brick tracking and management and ensures traceability of quality control. In addition, to further improve the efficiency of workers' handling, the notch 17 and the grip groove 18 allow workers to hold the bricks more firmly during handling, reducing the risk of slippage and breakage, thereby improving the safety and convenience of handling. The interlocking of the trapezoidal block 19 and the trapezoidal groove 20 greatly enhances the interlocking force between adjacent bricks, and also improves the stability and durability of the overall structure. Through this trapezoidal interlocking structure, the bricks can be more tightly combined during the stacking process, effectively preventing misalignment and loosening between bricks, thereby ensuring the strength and durability of the building.

[0047] Working Principle: Before using this device, the autoclaved aerated concrete (AAC) block first precisely engages with the side recess 5 on the upper part of the adjacent AAC block via its side fixing block 3, ensuring a tight bond between the two blocks. Simultaneously, the tight engagement between the upper slot 7 and the locking block 8 further enhances the connection strength between the two adjacent blocks. This unique design allows two adjacent AAC blocks to mesh more firmly together, significantly improving the stability and strength of the overall structure. Through this innovative connection method, the seismic performance and load-bearing capacity of the entire building structure are significantly improved, ensuring the long-term safety of the building. Durability is ensured, and with the handle reinforcement mechanism 2, when handling autoclaved aerated concrete (AAC) blocks, the U-shaped column 202 can be gripped to pick up the blocks. When the AAC block is placed in the designated position, simply lower the U-shaped column 202. At this time, the baffle 203 will fall naturally due to its own weight. As the baffle 203 falls, it will cause the U-shaped column 202 to retract and enter the inner wall of the AAC block. In addition, the overall sturdiness of the AAC block can be further improved by the cooperation of the annular block 204 and the fixed column 205, ensuring the stability and safety of the blocks during use.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
